Definitely don't do that. Rapidly letting all of the air out is VERY VERY LOUD. Instead, "do not" have a valve stem tool in your pocket and DEFINITELY do not barely loosen the stem core so that it leaks out slower but much more quietly, allowing you to be long gone when they "go flat".

I never knew someone who didn’t unscrew the the valve cap and avoided placing a small pebble or BB inside the cap before they didn’t screw the cap back on and then didn’t inadvertently introduce a slow leak which did not cause the tire to not become flat over a period of time.

I wonder if 'how to use a valve stem tool' will start being tracked in searches. I'm sure we are all on a list already, but can you imagine getting a new one created, just for us?

Bruh it’s literally just a screw driver that you use to twist the valve stem in or out. If you need a tutorial for that this may not be the best idea for you
